Re:   TrimTrac ProE SAR report, GPRS Class 8 operation

To whom it may concern:
The TrimTrac ProE conserves battery life via the operating system in microcode which
forces the Enfora model GSMO0308—10 (Enabler III—G) to use it‘s default configuration of
GPRS Class 8, which has only one uplink time slot. One uplink time slot has a 12.5%
duty cycle.

Although the Enabler III—G is designed to be capable of GPRS Class 10 operation, using
up to two uplink time slots, this capability of the module can never be selected by the
user or service provider.

SAR testing for TrimTrac ProF has used the duty cycle = 12.5%.
